Detailed Description

This class is designed to probe an underlying ns3 TraceSource exporting an ns3::Time.

This probe exports a trace source "Output" of type double, in units of seconds. The Output trace source emits a value when either the trace source emits a new value, or when SetValue () is called.

The current value of the probe can be polled with the GetValue () method.
